Bottom Bracket Problem on Trek 800 Mountain Bike
Have been trying to tune up my granddaughter's Trek 800 Mtn bike. Dates from the 90s so its not worth much but still in overall decent shape except....major wobble in the crankset. Removed the cranks and the adjustable cone but cannot get the spindle to come out. Tried to removed the fixed side cone but no matter how much liquid wrench and how much pressure I apply it seems in there for good. The bearings on the adjustable side were totally shot. Out of the retainer. Guess is that's the case on the fixed side also. There does not seem any good reason why I should not be able to slide the spindle out from the adjustable side; have done so many times on road bikes. LBS suggested it might be a jammed plastic sleeve protector but the spindle will move just so far and that is it. Does not feel like a plastic protector is blocking its exit. Can't move the fixed cone either way but just to be sure it does unscrew clockwise, right?
